Genetic analysis of bacteriophage Mu-induced flagellar mutants in Escherichia coli.
In previous work, at least 10 discrete cistrons involved in the synthesis of flagella in Escherichia coli were described. Six cistrons were located between his and uvrC on the genetic map. These were referred to as hag, flaA, flaB, flaC, flaD, and flaE. Four cistrons referred to as mot, flaG, flaH, and flaI were located between uvrC and aroD. In order to determine whether these genes are organi...
متن کاملBacteriophage Mu-1-induced permeability mutants in Escherichia coli K-12.
Apparent permeability mutations were produced in Escherichia coli K-12 by bacteriophage mu-1 mutagenesis. They are pleiotropic mutations showing sensitivity to a number of detergents and unrelated antibiotics, and presumably they affect cell wall or membrane biosynthesis. One of the mutations was genetically mapped at a site in or near the acrA and mtc loci at approximately 10.5 min on the Tayl...
متن کاملPasteurella Bacteriophage Sex Specific in Escherichia coli.
Phage H, thought to be specific for Pasteurella pestis, was shown to plate efficiently on F(-) strains of Escherichia coli but not on F(+), F', or Hfr strains. The phage was adsorbed rapidly to F(-) strains but was not adsorbed to strains carrying F. Comparison with seven other reported female-specific phages showed that, although phage H was similar to the other phages in some characteristics,...
متن کاملIsolation and mapping of Mu nu mutants which grow in him mutants of E. coli.
Mu nuA and Mu nuB mutants were selected by their ability to form plaques on lawns of Escherichia coli himA and himB mutants, respectively. Deletion mapping of the nuA and wB mutations by marker rescue from XpMu transducing phages or from hosts containing deleted Mu prophages indicated that nuA mutations are located within or to the left of gene A and that nuB mutations are located within or bet...
متن کاملIn Vitro Biocontrol of Escherichia coli Through the Immobilization of its Specific Lytic Bacteriophage on Cellulose Acetate Biodegradable Film
Background and Aims: Bacteriophages are mandatory bacterial parasites that are harmless to human and animal, which are used by dipping or spraying in food as natural antimicrobial agents. The use of these methods leads to wasting or trapping of phage in food, but its immobilization on the polymer surface facilitates the contact of phage with the host cell at the food surface. Therefore, the aim...
